GLOBE MOUNTING.

Application filed March 10, 1923. Serial No. 624,176.

To all whom it may concern:

, Be it known that I, HUGAR W. BAIRD, a citizen of the United States, residing at Chicago, in the county of Cook and State of Illinois, have invented a new and useful Improvement in Globe Mountings, of which the following is a specification.

This invention relates to improvements in globe mounting. The invention will be fully described in the following specification and accompanying drawings, in which Fig. 1 is a view in side elevation of a device embodying the features of my invention. Fig. 2 is a view taken as indicated by line 2 of Fig. 1.

As shown in the drawings, 10 indicates a pillar or stand suitably supported in any ,manner such as by a flat base or leg (not shown) so that the complete mounting may be stood on a table or other support. Piv' oted in the upper end of the pillar 10 is a frame comprising four upwardly curved arms, supporting on their upper ends the horizon ring 12. Rotatably mounted in the horizon ring is a meridian ring 13 which supports the sphere 15 at two diametrically opposite points 14.

As here shown, the meridian ring is sup ported in two diametrically arranged slots 16 in the horizon ring and rests on the small roller 17, arranged at the intersection of the four curved arms 11. The particular means of supporting the horizon ring and mounting the meridian ring, or supporting the sphere, constitute no part of the invention. It is obvious that these may be arranged in a variety of ways.

The particular features of my invention relate to the horizon ring. This ring ordinarily contains on its upper surface the signs of the zodiac, the names of the months, degree marks, and other desired symbols and markings. Heretofore such horizon rings have been made flat on top with the result that the markings thereon were visible only from points lying above the plane in which the ring lies. My invention consists of making the outer surface of this ring beveled as indicated by 18 so that the lower edge 19 of this outer surface is lower than the upper edge 20. In other WOICIS, the flat upper surface of the horizon ring which bears the markings .is slanted downwardly and out wardly. By this construction, the markings thereon, as suggested by 25, in Fig. 1, are

visible not only from. points lying above the the eye of the observer. This is one of the best angles from which to View the sphere since in this position practically all points of the sphere can be observed by rotating it on its. polar axes. WVith my improved mounting, when the sphere is so viewed the observer can readily see the markings on the horizon ring. IVith the old construction, if the sphere was viewed from points lying substantially in the plane of the horizon. ring, the markings could not be seen and if the observers eye was raised above the plane of this ring tO PGIII1lt observation of the markings thereon, a considerable part of the sphere lying below the ring was obscured.

While I have shown and describedfcertain embodiments of my invention, it is to be understood that it is capable of many modifications. Changes therefore in the construction and arrangement may be made without departing from the spirit and scope of the invention as disclosed in the appended claim, in which it is my intention to claim all novelty inherent in my invention as broadly as possible in view of the prior art.

hat I claim as new, and desire tosecure by Letters Patent is:

A globe mounting comprising a horizon ring having an exposed indicia-bearing frusto-conical surface terminating adjacent the surface of the globe, whereby to render such indicia readily readable from plane approximately that of such ring.

In witness whereof, I have hereunto set my hand and seal this 7th day of March A. 1)., 1923.
